I am running iTunes 11 on Mountain Lion, and I am subscribed to several podcasts. All of them work except one: With that one, new episodes are found, but every time I try to download one I get an exclamation point next to the name. If I copy the URL from the episode and paste it into a browser, I can download the file so I don't know why iTunes is failing. Is there a way to see an error message? I looked in Console and did not see anything.
Yes, when you are downloading episodes in iTunes 11, this icon shows up:
Click it and you can open your download progress:
If downloading fails, an error message will show up to the right of the status bar with an error code. You can Google this code for info. In my experience, this downloader is very unreliable if you have anything else downloading at the same time, or if you allow simultaneous downloads, although if you allow simultaneous downloads it generally finishes quicker if there are no errors.
